CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of U.S. Provisional Application No. 62/900,885, filed Sep. 16, 2019, the contents of which are incorporated herein by reference in their entirety.

FIELD OF THE INVENTION

The present disclosure provides an oral data collection device, a medical analytics system, and methods of using the device and system.

BACKGROUND OF THE INVENTION

Significant medical advancements in conjunction with higher computing power, lower hardware cost, and improved data management have led to an approach using a medical analytics approach to healthcare to be more holistically understood. In this era, there is a great deal of interest in wearable devices with functionality to collect up-to-date real-time health data.

Within the oral region of the human body, there are many other opportunities for the collection of invaluable health indicators. For instance, concern about injuries that occur during sporting activities has increased. In particular, head traumas that can result in concussion have come under greater scrutiny. According to the US Centers for Disease Control and Prevention (CDC), more than 3.8 million sports brain injuries occur per year with 300,000 resulting in loss of consciousness (LoC). These injuries are not limited to occurrence at the professional or collegiate level, but also include an estimated number of 25,000 sports brain injuries occurring at the high school level. Diagnosis and treatment of such injuries can be enhanced by monitoring athletes during the sporting events that can result in concussions and other head injuries. Importantly, oral health data can also be used to diagnose, monitor, and treat health conditions in a subject. For instance, oral data during sleep can provide invaluable information on a number of oral conditions and other health conditions that exhibit in data collected in the oral cavity, including bruxism, xerostomia, and PTSD. However, to date, there are no capabilities to continuously measure oral data during sleep. For instance, besides using the symptoms of bruxism that may be exhibited in the subject, including headaches, muscle soreness, daytime jaw discomfort/wear, and stress, methods of diagnosing or tracking the development of bruxism do not currently exist.

Accordingly, there is a need in the art for devices, systems, and methods of collecting oral data, especially oral data in the fitness and sports field, as well as when a subject is sleeping.

I. Device

One aspect of the present disclosure encompasses an oral data collection device. The device comprises a mouthguard with two or more sensors, a controller, a means for communicating sensor data, and a power source. The one or more sensors, controller, and power source are enclosed in the body of the device.

The mouthguard comprises an arch-shaped body comprising an external surface, an internal surface, a first biting surface, and a tray operable to engage a user's upper or lower teeth, the tray comprising a second biting surface opposite the first biting surface. It will be recognized that the arch-shaped body and the tray are of a size and shape appropriate for engaging with, and securing the mouthguard to the teeth of a wearer.

Materials suitable for manufacturing the mouthguard will be apparent to an individual of skill in the art. For instance, materials for the mouthguard may include, but are not limited to, one or more of the following materials: plastic, rubber, gel, metal, ceramic, and glass. Further, the mouthguard can be manufactured using more than one material. For example, the tray of the mouthguard can be manufactured of material suitable for securing the mouthguard to the teeth, whereas the body of the mouthguard can be manufactured using a material suitable for the function and protection of elements enclosed within the body of the mouthguard. The material could also be chosen to provide comfort for the wearer. Methods of manufacturing the mouthguard can and will vary depending on the material used for the product and the configuration of the product among other variables. For instance, the mouthguard can be manufactured using blow molding methods.

The device comprises one or more pressure sensors in the body of the mouthguard. Each sensor is operable to sense biting force exerted by the upper and lower teeth of the subject at the first and second biting surfaces. Pressure sensors are instruments or devices that translate the magnitude of the physical pressure exerted on the sensor into an output signal that can be used to establish a quantitative value for the pressure. There are many different types of pressure sensors known in the art, which function similarly but rely on different underlying technologies to make the translation between pressure and an output signal. Non-limiting examples of pressure sensor technologies include:

-   -   Potentiometric pressure sensors. Potentiometric pressure sensors         use a Bourdon tube, capsule, or bellows which drives a wiper         arm, providing relatively course pressure measurements.     -   Inductive pressure sensors. Inductive pressure sensors use a         linear variable differential transformer (LVDT) to vary the         degree of inductive coupling that occurs between the primary and         secondary coils of the transformer.     -   Capacitive pressure sensors. Capacitive pressure sensors use a         diaphragm that is deflected by the applied pressure, which         results in a change in the capacitance value, which can then be         calibrated to provide a pressure reading.     -   Piezoelectric pressure sensors. Piezoelectric pressure sensors         rely on the ability of materials such as ceramic or metalized         quartz to generate an electrical potential when the material is         subjected to mechanical stress.     -   Strain gauge pressure sensors. Strain gauge pressure sensors         rely on a measurement of the change in resistance that occurs in         a material such as silicon when it is subjected to mechanical         stress, known as the piezoresistive effect.     -   Variable reluctance pressure sensors. Variable reluctance         pressure sensors make use of a diaphragm that is contained in a         magnetic circuit. When pressure is applied to the sensor, the         diaphragm deflection causes a change in the reluctance of the         circuit and that change can be measured and used as an indicator         of the applied pressure.

A pressure sensor suitable for a device of the instant invention can be any pressure sensor having an appropriate size and shape suitable for functionally enclosing the sensor in the body of the mouthguard, and capable of withstanding and measuring the entire range of a human's biting force, including the biting forces generated during bruxism. Biting during bruxism produces a pressure of about 100 lbs to 200 lbs (or about 2000 kPa). Accordingly, a pressure sensor of the disclosure can measure and withstand at least a pressure ranging from about 1 to about 5000 kPa, from about 100 to about 4000 kPa, or from about 100 to about 2000 kPa.

A pressure sensor can be a membrane pressure sensor or a force plate pressure sensor among others. In some aspects, the pressure sensor is a force plate sensor. Force plate sensors use one of several different types of sensors (load cells) to measure forces. Beyond vertical force, some force plate sensors can measure shear forces—i.e. lateral and horizontal forces. In some aspects, the pressure sensor is a force plate sensor. In some aspects, the pressure sensor is capable of measuring shear forces. In some aspects, the pressure sensor is a force plate pressure sensor capable of measuring shear forces. Commercially available force plate pressure sensors suitable for use in a device of the invention include MD30-60 Resistance-Type Thin Film Pressure Sensor, and the FC2311-0000-2000-L Force Sensors & Load Cells high compression load cell.

Pressure sensors suitable for the instant disclosure are operable to extrapolate velocity of movement (m/s), power (Watts), displacement (Meters), temporal parameters (seconds), and left/right asymmetry for bilateral systems. In conjunction with other measurements of the oral cavity of a subject such as 3D imaging of the oral cavity, force plate pressure sensors can calculate and predict tooth location and movement, in addition to measuring the biting force. Such measurements can enable a frame-by-frame video/playback view of tooth location and movement that, when mapped out over time, could predict the future state of oral health and placement, thereby allowing preventive measures to prevent such movement or the damage resulting from these movements.

In some aspects, the device comprises one or more pressure sensors at the first distal end of the body, one or more pressure sensors at the second distal end of the body, or one or more pressure sensors at the first distal end of the body and one or more pressure sensors at the second distal end of the body. Each sensor is operable to sense biting force exerted by the upper and lower molars of the subject at the first and second biting surface. In some aspects, the device comprises a pressure sensor at the first or second distal end of the mouthguard. In other aspects, the device comprises a first pressure sensor at the first distal end of the mouthguard and a second pressure sensor at the second distal end of the mouthguard.

In some aspects, the pressure sensor is a pressure sensor stack. Accordingly, the device comprises one or more pressure sensor stacks. The pressure sensor stack comprises at least two sensors arranged in a stack. In some aspects, the pressure sensor stack comprises a first pressure sensor and a second pressure sensor, wherein the first sensor is operable to sense the biting pressure of a bottom molar, and the second sensor is operable to sense the biting pressure of a top molar. In some aspects, the device comprises one or more pressure sensor stacks at the first distal end of the body, one or more pressure sensor stacks at the second distal end of the body, or one or more pressure sensor stacks at the first distal end of the body and one or more pressure sensor stacks at the second distal end of the body. Each sensor is operable to sense biting force exerted by the upper and lower molars of the subject at the first and second biting surface. In some aspects, the device comprises a pressure sensor stack at the first or second distal end of the mouthguard. In other aspects, the device comprises a first pressure sensor stack at the first distal end of the mouthguard and a second pressure sensor stack at the second distal end of the mouthguard.

The device also comprises a humidity sensor enclosed in the body of the mouthguard. The humidity sensor is operable to detect relative humidity in the breath of a user wearing the device. A humidity sensor suitable for a device of the instant invention can be any humidity sensor having an appropriate size and shape suitable for functionally enclosing the sensor in the body of the mouthguard. Further, a humidity sensor suitable for use in a device of the invention is generally waterproof to be capable of measuring relative humidity in the breath of a user, in the presence of saliva. Non-limiting examples of humidity sensors suitable for a device of the invention include the HIH-4000-004 humidity sensor from Honeywell, and HDC 1080 sensors from Texas Instruments.

The humidity sensor is enclosed in the body of the mouthguard such that a sensing surface of the sensor is in physical contact with the breath of the wearer. Further, the humidity sensor is in a location in the body of the device such that a sensing surface of the sensor is in optimal contact with exhaled or inhaled breath. For instance, a sensing surface can be in a cavity in the body of the mouthguard adjacent to, and in functional communication with an aperture extending from the external surface to the internal surface at the proximal end of the body of the mouthguard, wherein at least the sensing surface of the sensor is in contact with the breath of the user. Alternatively, the sensing surface is at the surface of the mouthguard at a location in the mouthguard capable of providing optimal contact with exhaled breath. For instance, the sensing surface can be at the internal surface of the mouthguard. In some aspects, a sensing surface of the humidity sensor is located off center at the internal surface of the proximal end of the mouthguard. In one aspect, the sensing surface of the sensor is located at left of center at the internal surface of the proximal end of the mouthguard. In another aspect, the sensing surface of the sensor is located right of center at the internal surface of the proximal end of the mouthguard.

A suitable humidity sensor can sense relative humidity in a range encompassing the relative humidity of the breath, including the low relative humidity of a user with xerostomia or halitosis. Xerostomia or dry mouth is a common, but sometimes overlooked, condition that is typically associated with salivary gland hypofunction (i.e., the objective measurement of reduced salivary flow). Reduced salivary flow can cause difficulties in tasting, chewing, swallowing, and speaking; it can also increase the chance of developing dental decay, demineralization of teeth, tooth sensitivity, and/or oral infections. There are a variety of potential causes of xerostomia, including adverse effects of medication, toxicity of chemotherapy and/or radiation therapy of the head and neck, autoimmune disease, other chronic disease, and nerve damage. Halitosis—or chronic bad breath—is something that mints, mouthwash or a good brushing cannot solve. Unlike “morning breath” or a strong smell that lingers after a tuna sandwich, halitosis remains for an extended amount of time and may be a sign of something more serious. Halitosis can be an indication of health conditions in the subject, including cavities and gum disease, mouth, nose and throat infections, dry mouth including xerostomia, smoking, tobacco, or other chronic conditions such as gastric reflux, diabetes, and liver or kidney disease.

Within the oral region of the human body there are many other opportunities for invaluable human information and health indicators to be more holistically understood. Accordingly, the device can further comprise sensors for use in collecting oral data in addition to biting pressure and relative humidity in the breath. Non-limiting examples of sensors include a temperature sensor, a microphone or vibration sensor, an oxygen sensor, a nine-axis inertial sensor, a pH or other biochemical sensor, or combinations thereof. Such sensors are known in the art, and suitable sensors can be identified experimentally. Other sensors capable of sensing oral biometric data are apparent to an individual of skill in the art.

In some aspects, the device comprises a temperature sensor. Body temperature has been measured orally for centuries, but has not been measured during sleep to measure parameters collected in conjunction with sleep phases, body position, hydration, and time, which in itself can reveal one's quality of sleep and habits at night. A temperature sensor can be, e.g., a diode type sensor, an external low-power temperature sensor such as the Texas Instruments LM94022 multi-gain sensor, or other appropriate type of temperature sensor. The temperature sensor can be operable to record oral temperatures, thereby providing potential heat-related oral and general health of a user. In some aspects, the temperature sensor can be an integrated humidity and temperature sensor. Such integrated sensor can include, e.g., the HDC 1080 sensors from Texas Instruments.

In some aspects, the device comprises a microphone or vibration sensor. A microphone or vibration sensor can be useful in detecting breathing patterns during sleep. The human breath soundwaves can provide information related to breathing conditions such as sleep apnea and snoring. The microphone/vibration sensor can be a unit similar to that of a 801S Vibration Sensor Module vibration Analog Output Sensitivity LM393 within the mainstream market. In some aspects, the microphone or vibration sensor is enclosed in an acoustic chamber in the body of the device. In some aspects, the microphone/vibration sensor is at the proximal end in the body of the mouthguard in an acoustic chamber that collects the soundwave of the human breath. In some aspects, the microphone/vibration sensor is in a protective compartment as described further below, wherein the protective compartment collects the soundwave of the human breath.

In some aspects, the device comprises a nine-axis inertial sensor enclosed in the body of the mouthguard. The inertial sensor comprises a three-axis magnetometer, a three-axis accelerometer, and a three-axis gyroscope, the three-axis magnetometer operable to provide a reference plane in relation to the earth's magnetic field for the three-axis accelerometer and the three-axis gyroscope. The nine-axis inertial sensor is adapted to sense the position and movement of the head and body of a subject wearing the device. Within the field, accelerometers have been used to detect impact during athletic activities, most notably within a football helmet that is connected to a mouthguard. In some aspects, the inertial sensor is located in the body of the mouthguard, at the proximal end of the mouthguard. Use of an inertial sensor in a device of the instant disclosure can detect the sudden/gradual movement of the head, the body, or both. For instance, the inertial sensor can track if an individual is upright, sleeping sideways, on back, or on belly which plays a large role with numerous medical and psychological indicators and patterns such as nightmares, stress, PTSD, or sleep apnea.

The device comprises a controller in the body of the mouthguard. The controller is in functional communication with the two or more sensors, and is operable to receive and communicate sensor data. In addition to receiving sensor data, the controller can include additional input components that permit input by a user (e.g., a touch screen display, a keyboard, a keypad, a mouse, a button, a switch, a microphone, etc.). The controller can also include output components that provide output information (e.g., a display, a speaker, one or more light-emitting diodes (LEDs), etc.).

The device further comprises a means for communication enclosed in the body of the device. The means for communication is operable to receive the sensor data from the controller and communicate the sensor data to a secondary device. The means for communication may include a transceiver-like component (e.g., a transceiver, a separate receiver and transmission source, etc.) that communicates the sensor data received by the controller to a secondary device, such as via a wireless connection using a wireless communication protocol, a wired connection, or a combination of wired and wireless connections. A wired connection can include an Ethernet interface, an optical interface, a coaxial interface, an infrared interface, a universal serial bus (USB) interface, and/or the like. A wireless communication protocol can include an NFC communication, a Radio-frequency identification (RFID) communication, Bluetooth, LTE, ZigBee, LoraWAN, Wi-Fi, and/or the like. In some aspects, the means of communication comprises a transmitter operable to communicate the oral data to the secondary device wirelessly using a wireless communication protocol. In some aspects, the means of communication comprises a transmitter operable to communicate the oral data to the secondary device wirelessly using Bluetooth.

The secondary device can be a stationary computing device such as a desktop computer. Alternatively, the secondary device can be a mobile computing device such as a cellular phone (e.g., a smartphone or standard cellular phone), a portable computer (e.g., a tablet computer, a laptop computer, etc.), a wearable device (e.g., a watch, a pair of glasses, a lens, clothing, and/or the like), a personal digital assistant (PDA), a computing device with no user interface, a cloud computing platform, and/or other like devices.

The device further comprises a power source functionally coupled to the controller and the two or more sensors. The power source can be a wired connection to an external power source. For instance, the power source can be rechargeable through a port defined in the device. The power source can also be a power storage device such as a conventional battery, capacitor, or electromagnetic power source. The power source can be removable, replaceable, rechargeable, and combinations thereof. For instance, if the power source is rechargeable, the power source can be rechargeable wirelessly or through a wired connection to an external power source. The power source can also be rechargeable by an electric generator that is powered by mechanical energy received from the subject. In this aspect, the electric generator can be configured to convert mechanical energy applied to the mouth guard by the subject (through, for example, biting down) into electrical energy.

In addition to the controller, the device can further comprise at least one processor and associated memory adapted to receive sensor data from the controller. In some aspects, the processor can be operable to assign one or more event times, wherein each event time indicates the time of a change in the state of a signal received from a sensor. In this aspect, the associated memory can be operable to receive and store the signals and/or outputs of the sensors of the device, and the one or more event times. The storage component may store information and/or software related to the operation and use of the controller. The storage component can include a random-access memory (RAM), a read only memory (ROM), and/or another type of dynamic or static storage device (e.g., a flash memory, a magnetic memory, an optical memory, etc.) that stores information and/or instructions for use by the controller.

In some aspects, it is contemplated that the processor can comprise means for generating an alarm in response to one or more inputs from a sensor. In these aspects, it is contemplated that the means for generating an alarm can comprise a conventional device for selectively generating optical, thermal, vibrational, and/or audible alarm signals.

Other components that may be included in the device can be a power button, controls for operating one or more components of the device, a component that provides output information from the controller (e.g., a display, a speaker, one or more light-emitting diodes (LEDs), etc.), or combinations thereof. For instance, when the means for communication is a Bluetooth module, the controls can be used to connect and pair the device to the secondary device. In some aspects, the power button can also be used as a means for controlling one or more of the components of the device.

It will be recognized that one or more of the components of the device, including the one or more sensors, the controller, the means for communication, the power source and any other electronic components, can be integrated onto a single circuit board for space saving. Further, one or more of the one or more sensors, the controller, the means for communication, the power source and any other electronic components can be enclosed in a protective compartment in the body of the mouthguard. For instance, the protective compartment can be water resistant, and can protect the components from biting forces and from the environment in the oral cavity, including saliva. The protective compartment can be sealed or can comprise a resealable opening for access to the components. In some aspects, one or more components of the device, including sensors, controllers, and communication means, are enclosed in a protective compartment in the mouthguard. In some aspects, when the protective compartment comprises a microphone/vibration sensor, the protective compartment is operable to provide an acoustic chamber that collects the soundwave of the human breath.

II. Methods

Another aspect of the present disclosure encompasses methods of collecting oral data in the oral cavity of a subject. In a method of the invention, the device is worn by the subject by positioning the device in engagement with at least one of the upper teeth or the lower teeth of the subject. In some aspects, the device is worn by the subject during sleep. In other aspects, the device is worn by the subject during exercise. In operation, it is contemplated that data points can be collected and then processed according to a predetermined algorithm, such as a series of equations and/or lookup tables. For instance, the data can be used to assign one or more event times, wherein each event time indicates the time of a change in the state of a signal received from a sensor. Further, data points collected and/or assigned event times can be translated into health score using a predetermined algorithm.

The collected oral data or the event times or health score derived from the data can be used in determining a personalized treatment protocol, staging a given health condition, measuring response to therapy, phenotyping for selection to participate in drug trials, measuring stability of an anatomical structure, or predicting rate of change of the given disease in a subject in need thereof. The subject has or is suspected of having one or more health conditions in the oral cavity or a health condition exhibited in the oral cavity. As used herein, the term “exhibited in the oral cavity” refers to symptoms of health conditions in the subject other than health conditions in the oral cavity, but can be detected using biometric data collected in the oral cavity. Non-limiting examples of health conditions include concussions and head injuries, bruxism, xerostomia, sleep apnea, nightmares, PTSD, anxiety, insomnia, tooth infection, tooth decay, tooth damage, and psychological disorders such as psychosis, sleep walking, and combinations thereof among other disorders. In some aspects, the health condition is bruxism. In other aspects, the health condition is xerostomia.

The method further comprises using the oral cavity data collected from the subject to develop a database of biometric measurements obtained from the subject alone or in combination with data measurements obtained from other subjects, for providing information to the subject or healthcare provider regarding historical physiological characteristics of the subject, thereby providing a means for determining health conditions and unusual behaviors. The collected data can be used in combination with descriptive information comprising one or more data elements relating to the subject. The data elements can include the results of clinical tests normally performed during a regular visit by the subject to a physician, including weight, height, blood pressure, pulse, and results of blood tests such as cholesterol levels, comprehensive metabolic panel, and lipid panel, among others. The data elements can also include information and results of clinical tests obtained during diagnosis of a health condition. For instance, when the health condition is bruxism, non-limiting examples of data elements can include tooth wear, headaches, anxiety, jaw pain, abnormal sleeping patterns, changes in sleep positioning, changes in bite force distribution, changes in movement while sleeping, sleep loss, behavioral changes (e.g., heightened stress, anxiety), and combinations thereof.
